日冕的电离气体(又叫等离子体)不仅非常炙热,而且异常稀薄,其密度还不到组成太阳主体的氢气密度的十亿分之一。
As well as being very hot, the ionised gas of the corona (called plasma) has a superthin consistency. It is less than a billionth of the density of the hydrogen that makes up the main ball of the Sun.
电场沿磁力线传到F_2层,通过“喷泉效应”引起电离层赤道异常的行星波振荡。
The electric field can transfer to F2 region along the geomagnetic field line and by means of the fountain effect it can results in the PSO of the equatorial anomaly.
太阳辐射电离与热层中性风的竞相联合作用是导致夏季异常的关键。
Summer anomaly can be explained by combining effects of two competing cause, thermospheric winds and solar effects on ionosphere.
